Trolling should be a bannable offense. Not just account banned, but console banned. It's probably an alt account anyway. If you ban the console, mommy and daddy will get tired of buying new consoles for the little turds.

Other day got corner trapped by some troll in a game of SnR. He kept shooting to give away our positions but the funny thing was that the enemy team found us killed him and didn't even notice I was there! Sometimes justice is served.

The trend is growing more and more. I almost stopped playing Black Ops 2 due to the community. Something needs to be done. I think Microsoft or Activision should update their TOS to address the situation.

When someone from the other team is trying to give away your position I've found that usually they have one from there friends list on the other team which then means high probability that they are boosting and is reportable. ...

report and and then mark them as avoid player if they continue to do this then it could be considered harassing which is also reportable.

are you using a mic ? i am asking this part for the blocking your path portion ,, they may have sit rep on and see your walking right into a trap and if you don't have a mic they may actually be trying to help on that part of it....or prevent the spawn from flipping ,,, I'm just saying that sometimes there may be a reason for blocking a path it may or may not be the case but not every time is it meant as a bad gesture.
